Testing that Sidekiq received correct delayed job

Question

Inside of my User model I'm calling a delayed method:

class User < ActiveRecord::Base
  def self.import_items
    ...
    User.delay.keep_only_user_cars(1) # "1" is just for testing
  end
end

And I'm trying to test it like so (using rspec-sidekiq gem):

expect(Sidekiq::Extensions::DelayedClass).to have_enqueued_job("keep_only_user_cars", 1)     

This is what I get:

Failure/Error: expect(Sidekiq::Extensions::DelayedClass).to have_enqueued_job("keep_only_user_cars", 1)
  expected to have an enqueued Sidekiq::Extensions::DelayedClass job with arguments ["keep_only_user_cars", 1] but none found
  found: [["---\n- !ruby/class 'User'\n- :keep_only_user_cars\n- - 1\n"]]

Which basically works, just has a bit different formatting.

How do I fix this test to make sure that Sidekiq received exactly this method with exactly this attribute?

According to the docs, the delay extensions send the entire object in redis, not just the values. If you want to test for that object, you'd need to use YAML.dump(object):

expected = YAML.dump([User,:keep_only_user_cars,1])
expect(Sidekiq::Extensions::DelayedClass).to have_enqueued_job(expected)
